Benefits of technology

This approach optimizes peak current consumption and prevents deadlock phenomena, thereby enhancing the operational performance and reliability of the semiconductor device.

Problems solved by technology

During an operation of a semiconductor device, there may occur a period in which a peak instantaneous current flows in the semiconductor device, thereby consuming more power than the average power consumed by the semiconductor device.
When the semiconductor device includes a plurality of chips and the plurality of chips simultaneously perform respective peak zone operations, a failure may occur in the semiconductor device due to excessive current consumption.
As a result, the operation performance of the conventional semiconductor device is deteriorated.
As described above, the conventional semiconductor device 10 has a drawback that the operation performance is deteriorated for power management, and the operation of the device 10 is interrupted under certain conditions.

Embodiment Construction

[0031]Hereafter, various embodiments will be described below in more detail with reference to the accompanying drawings.

[0032]FIGS. 2, 3, and 4 are block diagrams respectively showing semiconductor devices 100-1, 100-2, and 100-3, according to embodiments of the present disclosure.

[0033]Each of the semiconductor device 100-1 of FIG. 2, the semiconductor device 100-2 of FIG. 3, and the semiconductor device 100-3 of FIG. 4 includes a plurality of chips, e.g., chips 110-1 to 140-1 of FIG. 2, chips 110-2 to 140-2 of FIG. 3, or chips 110-3 to 140-3 of FIG. 4. Although four chips are shown in each of the embodiments, other embodiments may include a different number of chips.

[0034]Referring to FIG. 2, each of the plurality of chips 110-1 to 140-1 receives an input key and input token on an input port IP for power management and outputs an output key and output token through an output port OP. In an embodiment, the input key is the same key as the output key, and thus a single key circulate...

Abstract

A semiconductor device may comprise a plurality of chips coupled in a ring structure, and the plurality of chips includes a first chip. Each of the plurality of chips may include a key port receiving or outputting a key to circulate the key through the ring structure. The first chip is configured to be in a standby state until an amount of available token becomes equal to or greater than an amount of required token to perform a specific operation in the first chip, when the first chip has the key.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2016-0035066, filed on Mar. 24, 2016, which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field[0003]Embodiments of the present disclosure relate to a semiconductor device for performing power management and a method of operating the same, and more particularly, to a semiconductor device for performing power management based on one or more tokens and an operation method thereof.[0004]2. Description of the Related Art[0005]During an operation of a semiconductor device, there may occur a period in which a peak instantaneous current flows in the semiconductor device, thereby consuming more power than the average power consumed by the semiconductor device.[0006]A section corresponding to the period is called a peak zone (PKZ) and the operation including this section is called a peak zone operation.[0007]When the semiconductor device includes a ...
